I just installed three 4GB DDR3-1333 (PC3 10600 ) UDIMM 240-pin RAM stix into slots 1,3, & 5 of my Dell Studio XPS 435 System running Windows Vista Home Premium 64-bit OS which had 6 RAM slots with six 1GB RAM stix installed. After installation, I had trouble getting the PC to boot up. Finally, after several tries it did boot. I went to MyComputer and looked at its properties. It showed I had only 10GB RAM and not the 15 GB that I expected (three 4GB stix and three 1GB stix). I then went to the Crucial website (RAM stix seller) and ran its system scanner tool. It showed that one 4GB RAM slot and one 1 GB RAM slot were empty, but not which of the 6 slots/stix were empty/bad.
I called Crucial tech support. They suggested that I pull out all of the RAM stix and just install one stix in RAM slot #1. If the PC would boot, then repeat several times until I isolated which stix might not work in slot #1. If the 6 boots were successful, move to slot #2 and repeat. I said this would be extremely time-consuming in my office setup. I asked if there was any tool which could analyze my PC and they suggested Speccy.
I ran Speccy, and it also shows that I have 6 total memory slots and that only 4 are being used. When I look at the six slots individually, they all look like they have nearly identical information, i.e., they show nothing unusual about any of the slots. Is there any way for Speccy to show which memory slots/stix are not registering/functioning?
I tried to attach a Speccy snapshot, but your forum wouldn't allow it, so here is a copy/paste effort to show the Speccy screen for the RAM:

Can't locate bad RAM slot/stick
in Speccy
Posted
Interestingly, I did install the stix one at a time, and they all worked when only one was installed. However, when I installed all three of the new stix, the PC would not boot.
After reading about this same problem in a Dell Studio XPS 435MT owner's forum, I realized the Crucial RAM stix will not work "as a team" in my PC; others reported the same problem. So I sent the items back to Crucial and bought the PC "owners" recommendations from Kingston. I actually bought six 4GB RAM stix, installed them all, and they all work fine.
The only reason I posted my original post was to alert Speccy programmers that even when Speccy shows that not all of the installed RAM is summed to the correct total becaise of faulty RAM stix/slots, the Speccy data on the individual stix does not point out which stix/slots are bad. It seems like that might be a nice addition to an already good product.
